This package is already part of rector/rector package, so it works out of the box.

All you need to do is install the main package, and you're good to go:

composer require rector/rector --dev

Use Sets

To add a set to your config, use Rector\Symfony\Set\SymfonySetList class and pick one of constants:

use Rector\Core\Configuration\Option;
use Rector\Symfony\Set\SymfonySetList;
use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $containerConfigurator): void {
    // region Symfony Container
    $parameters = $containerConfigurator->parameters();
        __DIR__ . '/var/cache/dev/App_KernelDevDebugContainer.xml'
    // endregion


Read a First Book About Rector

Are you curious, how Rector works internally, how to create your own rules and test them and why Rector was born? In May 2021 we've released the very first book: Rector - The Power of Automated Refactoring.


By buying a book you directly support maintainers who are working on Rector.


Rector is a tool that we develop and share for free, so anyone can automate their refactoring. But not everyone has dozens of hours to understand complexity of abstract-syntax-tree in their own time. That's why we provide commercial support - to save your time.

Would you like to apply Rector on your code base but don't have time for the struggle with your project? Hire us to get there faster.
